By Samantha Grossman http://newsfeed.time.com/2012/09/14/cre ... cebook-ad/If you’re in the mood to draw ire from people with excruciatingly rigid beliefs, the Internet is generally a good place to start. While you’re at it, might as well pick a particularly polarizing topic. Why not evolution?

Now, that probably wasn’t exactly how the conversation went down over at the marketing offices of Dr. Pepper, but a recent ad for the soft drink posted on Facebook — with the slogan “Evolution of Flavor” — sparked a healthy dose of controversy nonetheless. Based on the iconic evolution diagram “March of Progress,” the ad features an ape who, after drinking Dr. Pepper, turns into a man. The ad went up Thursday, and by Friday had garnered more than 26,000 “Likes” and over 4,000 comments.
